Fig is different than Kickstarter or Indiegogo in that it offers both traditional, rewards-based backing and the option to invest in a game through equity.

The majority of funding for The Tower has come from investments ($224,000) with the remaining $78,000 derived from traditional pledges. The campaign ends on May 11, so it's likely even more money will pour in.

With the campaign now having met its target, developer Interdimensional Games has announced the first stretch goal. If funding reaches $350,000, the studio will add "Equipment Engineering."

"Find a major upgrade to your PCU in The Tower that allows you to break down items you recycle into three types of materials (Elements, Compounds, and Exotics) and them combine these materials with your equipment to apply various upgrades," reads a line from its official description. "Based on your preferences, your team will work with you to discover new upgrade 'recipes.'"

The Tower, a sequel to 2014's well-received PC game Consortium, is a single-player, first-person sci-fi game that takes place (almost) exclusively within a structure called the Churchill Tower in London 2042. All the core mechanics, interface systems, and gear from the original are back, but this time with an "all new scope." You can see the game in action through the video below.

"It's not just deriving itself from what other folks have done before; it's pushing new ground and trying to do things differently while maintaining sensible conventions," Zeschuk said.

The Tower is tentatively scheduled to launch sometime in the first three months of 2018 for PC, Xbox One, and PlayStation 4. You can guarantee yourself a copy by pledging $20, while a pledge of $2,000 gets you a beer-tasting experience with Zeschuk, who is opening a brewery in Canada.
